Claimer is seeking a startup operator / second-in-command to the CEO to help run and scale the business in the next growth phase. We’re an AI-native product that augments corporate tax advisors in their processes. We are currently pursuing a major customer-led pivot with a new brand and product, aiming to scale significantly in the next 6 months. After six years and two pivots, we are at a tipping point for product/market fit and traction, with enterprise design partners and 60+ existing customers. The broader market opportunity is the corporate tax advisory/professional services market in the UK, US, and beyond. The team is remote-first/hybrid and highly collaborative.
